Figures, you need at least the full_session variable.

But is DBUS_SESSION_BUS_ADDRESS set in the shell from which you launch dolphin? If not, it won't find the dbus to connect to.

I cannot help you with that, sorry. Maybe ask on the kdepim-users ML?

They are, but if you don't use the plasma-integration plugin and/or don't set the variables mentioned above, KDE applications will simply look like Qt applications, and won't use the font, colour, icon etc. settings defined for the plasma desktop.
I agree with you that this aspect should also be independent of what kind of desktop you run. That's why I answered your question :)

>BTW: Do you have any idea how to set dolphin to select on double click, not single click. I was looking at `kcmshell5 --list` but couldn't find the right module. Or is there even a command to get the KDE system settings GUI?

Try system-settings. The setting you look for exist, but I always forget where. You can also set if directly in ~/.config/kdeglobals: set SingleClick=false in the KDE section. NB: your KDE4 applications probably use a file of the same name that lives in ~/.kde*/share/config/kdeglobals .
